BACKGROUND OF INVENTION

[0001] 1. Field of Invention

[0002] The present invention relates to a carrier for packaging liquid crystal panels. More particularly, the present invention relates to an adjustable liquid crystal panel carrier.

[0003] 2. Description of Related Art

[0004] At present, liquid crystal panels are often packaged inside a carrier unit having an integrative design. In general, the liquid crystal panels are laid down flat inside a carrier or plugged into the specially designed slots of a carrier. Since the grooves for gripping each liquid crystal panel are normally fixed in dimension, a liquid crystal panel of one particular size can be accommodated inside the carrier. However, due to the rapid improvement in digital technologies, newer types of liquid crystal panel with a range of different dimensional designs are constantly developed. To accommodate newer versions of the liquid crystal panels, the carrier has to be redesigned and fabricated while the old ones have to be scrapped. This leads not only to a waste of material but also a waste of molding resources.

[0005] Furthermore, the material for fabricating an integrative carrier unit also has some important effects on protecting the liquid crystal panels being accommodated. If the carrier is fabricated using a harder material, the carrier can act as a rigid body to resist any deformation. On the contrary, if the carrier is fabricated using a softer material, the carrier can act as a buffer to absorb any shock or vibration. However, the conventional carrier can serve either as a rigid body resisting any deformation or a softer body resisting shock but not both. Furthermore, each liquid crystal carrier normally has a considerable number of interior slots rendering a proper cleaning difficult. If some chipped pieces happen to stick to the surface of a slot due to breakage of some liquid crystal panel, all liquid crystal panels subsequently lowered into the slot of the carrier may be scratched.

SUMMARY OF INVENTION

[0006] Accordingly, one object of the present invention is to provide a liquid crystal panel carrier having an adjustable interior partition to fit panel of various dimensions.

[0007] A second object of this invention is to provide a liquid crystal panel carrier that can minimize resource wastage.

[0008] A third object of this invention is to provide a liquid crystal panel carrier that buffers the panels against shock and protects the panel against damaging deformation.

[0009] A fourth object of this invention is to provide a liquid crystal panel carrier whose design prevents any loose chips from scratching the surface of the panels.

[0010] To achieve these and other advantages and in accordance with the purpose of the invention, as embodied and broadly described herein, the invention provides a first type of liquid crystal panel carrier. The liquid crystal panel carrier comprises a box and a plurality of attaching elements. The interior lateral surface of the box has a plurality of cannelures. The side edges at the respective ends of each attaching element are plugged into correspondingly positioned cannelures so that the interior of the box is partitioned into variable size compartments. The box is fabricated using a material harder than the attaching elements.

[0011] This invention also provides a second type of liquid crystal panel carrier. The liquid crystal panel carrier comprises a box and a plurality of attaching elements. The interior bottom surface of the box has a plurality of cannelures. The attaching elements are plugged into correspondingly positioned cannelures inside the box so that the interior of the box is partitioned into variable size compartments. The box is fabricated using a material harder than the attaching elements.

[0012] In this invention, the interior of the liquid crystal panel carrier is partitioned into compartments using movable attaching elements. Hence, the liquid crystal panel carrier can be refitted on demand to accommodate another panel having a larger or a smaller size simply by repositioning the interior attaching elements so that the size of each compartment is increased or decreased. In other words, the liquid crystal panel carrier can be used to package liquid crystal panels of whatever sizes.

[0013] Both the attaching elements and the box are replaceable. That means, a defective attaching element or box can be replaced individually so that material waste is maintained at the lowest level.

[0014] Furthermore, the attaching elements and the box can be manufactured using materials having a different density. For example, the external box structure is fabricated using a higher density material to prevent the attaching elements and the liquid crystal panels from being squashed or distorted due to an impact. Similarly, the attaching elements are fabricated using a lower density material to provide some flexibility for protecting the liquid crystal panels against shock and external impact.

[0015] In addition, the attaching elements can be taken out of the box. Thus, the box interior as well as the attaching elements can be thoroughly cleaned with ease.

[0016] It is to be understood that both the foregoing general description and the following detailed description are exemplary, and are intended to provide further explanation of the invention as claimed.

DETAILED DESCRIPTION

[0022] Reference will now be made in detail to the present preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers are used in the drawings and the description to refer to the same or like parts.

[0023]FIG. 1 is a top view showing a liquid crystal panel carrier assembly according to one preferred embodiment of this invention. As shown in FIG. 1, the liquid crystal panel carrier 100 comprises a box 110 and a plurality of attaching elements 116. The interior of the box 110 furthermore comprises a bottom surface 106 and pairs of oppositely positioned lateral surfaces 102 a, 102 b, 104 a and 104 b. The bottom surface 106 and all the lateral surfaces 102 a, 102 b, 104 a, 104 b have cannelures thereon including, for example, saw-tooth-like cannelures 112 b on the bottom surface 106, saw-tooth-like cannelures 112 a on the oppositely faced lateral surfaces 102 a, 102 b or dovetail grooves 114 on the oppositely faced lateral surfaces 104 a, 104 b. In addition, the positioning of the cannelures on the interior walls of the box 110 can be varied on demand. For example, cannelures may be formed on the lateral surfaces 102 a, 102 b, the lateral surfaces 104 a, 104 b or the bottom surface 106 only instead of on all the interior surfaces as shown in FIG. 1. Moreover, the box 110 may be fabricated using a material harder than the attaching elements 116 so that the liquid crystal panel carrier serves not only as a buffer but also a shield against liquid crystal panel deformation.

[0024] As shown in FIG. 1, the attaching element 116 has a plate-like structure with its edges plugged into corresponding cannelures inside the box 110 for partitioning the interior into variable size compartments. The edges of the attaching element 116 have a saw-tooth profile 118 that corresponds with the saw-tooth cannelures 112 a, 112 b so that the attaching element 116 can be firmly stationed inside the box 110. In other words, as long as the attaching elements 116 are firmly clamped inside the box 110, whether the bottom surface 106 or the lateral surfaces 102 a, 102 b or the lateral surfaces 104 a, 104 b have cannelures or not is not too important. Furthermore, the attaching elements 116 can be divided into two major types. One type of attaching element 120 a has a plurality of edges 122 protruding from each of its lateral surfaces. Hence, the edges 122 of any two neighboring attaching elements 120 a form an insertion slot 124 for accommodating a liquid crystal panel. In another type of attaching element 120 b, edges 122 protrude from one lateral surface while the other lateral surface has a plurality of clamping sections 126. The clamping sections 126 correspond in position to the dovetail grooves 114 for engaging the attaching element 120 b and the box 110 together.

[0025]FIG. 2 is a perspective view showing various dismembered components in the liquid crystal panel carrier assembly shown in FIG. 1. After finding the size of the liquid crystal panel to be packaged inside the box 110, the dimension of each compartment for accommodating the panel and the number of attaching elements 116 for partitioning the interior into useful compartments can be determined. Thereafter, the attaching elements 120 b are inserted into the lateral surface 104 a of the box 110 in a direction 200. Ultimately, the dovetail grooves 114 engage with the clamping sections 126 and the saw-tooth cannelures 112 a on the lateral surfaces 102 a, 102 b of the box 110 as well as the saw-tooth cannelures 112 b at the bottom surface 106 of the box 110 engage with the saw-tooth cannelures 118 of the attaching element 120 b. Afterwards, the attaching elements 120 a are sequentially inserted into the interior of the box 110 according to the pre-determined partition dimension. In other words, the saw-tooth cannelures 118 at the edges of the attaching element 120 a engages with the saw-tooth cannelures 112 a on the lateral surfaces 102 a, 102 b and the saw-tooth cannelures 112 b of the bottom surface 106. To explain the structural relation between the box 110 and the attaching elements 116, refer to the magnified views in FIGS. 3 and 4.

[0026]FIG. 3 is a magnified view of section III in FIG. 2. As shown in FIG. 3, the two ends and the bottom section of each attaching element 116 has saw-tooth cannelures 118. Furthermore, the lateral surface of the attaching element 116 has protruding edges 122 so that the protruding edges 122 of any two neighboring attaching elements 116 form a plugging slot 124 for accommodating a liquid crystal panel. The pitch 300 of the teeth in the saw-tooth cannelures 118 is about 5 mm, for example. Since the saw-tooth cannelures 118 are set on the edges of the attaching elements 116, the saw-tooth cannelures 118 can also be set on the surface of the protruding edges 122 at each end of the attaching element 116 as well as the bottom surface of the protruding edges 122.

[0027]FIG. 4 is a magnified view of section IV in FIG. 2. According to the embodiment, saw-tooth-like cannelures 112 a are set on the lateral surface 102 a of the box 110 and dovetail grooves 114 are set on another lateral surface 104 a of the box 110. The connecting section 400 between the lateral surface 102 a and the lateral surface 104 a is also shown in FIG. 4. With the dovetail grooves 114 serving as a cannelure imprint, the side with the saw-tooth cannelures 112 a separates from the connecting section 400 of the lateral surfaces 102 a and 104 a by a distance.

[0028] In summary, major characteristics of this invention include: 1. Attaching elements that can be relocated are used inside the liquid crystal panel carrier so that liquid crystal panels of various sizes can be accommodated. Hence, one type of carrier can be used to package all sorts of liquid crystal panels. 2. Since the attaching elements inside each liquid crystal panel carrier are replaceable, any damaged attaching element or box can be individually replaced to save material. 3. Unlike a conventional integrative liquid crystal panel carrier, the box can be fabricated using a material harder than the attaching elements so that the liquid crystal panels inside the box are protected against shock and vibration and at the same time the box is prevented from impact deformation. 4. Because the attaching elements can be taken out of the carrier, cleaning the interior of the box is relatively easy.

[0029] It will be apparent to those skilled in the art that various modifications and variations can be made to the structure of the present invention without departing from the scope or spirit of the invention.
